SWINGLETREE-I-IOOK.

Specification of Letters Patent.

Application filed August 9, 1917. SerialNo. 185,340.

To aZZ whom. t mag/concern:

Be it known that I, l/VAL'IER J. SPENCER, a citizen ofthe United States, residing at Ivanhoe, in the county of Lincoln and .State of Minnesota, have invented certain new and useful Improvements in Swingletree- 'Hooks, of which the following is a speciication.

This invention relates to an improvement in swingletree hooks; and it is a purpose to provide a hook of this character having parts associated therewith by which the traces are held against accidental or casual displacement.

A further object resides in so constructing the means associated With the hook, that very little interference is offered to the fitting of the traces upon the hook, andyet when the retaining mechanism moves into place it is locked against being bent or distorted in such away that the trace would be disconnected, through ordinary uses.

Yet another object is to construct the trace retaining member 0f a spring material so that as the trace is fitted to the hook, this retaining portion will spring back in place and will hold in this position until again manually released.

With the above and other objects in view, which will be in part described and in part understood from the specification, drawings, and claims, my invention consists in certain novel features of construction and combination of parts which Will be hereinafter more fully set forth.

In the drawings- Figure l is a View in elevation of a sWingletree hook constructed after the manner of my invention;

Fig. 2 is an elevational view taken at an angle to the disclosure in Fig. l; and,

Fig. 3 is a vieW in elevation showing a slightly modied form of retaining member.

The ferrule or ring 1 is adapted to be fitted and secured upon the end of the swingletree 2, in any desired and approved way, and the hook 3 is formed integral with or connected to this ferrule or ring 1, so that when the member 1 is fitted upon the end of the sivingletree the 'hook is disposed in the proper relation to be tted through the eye 4 of the trace 5.

The parts as above set forth can be to all intents and purposes of substantial standard forirs and designs, except that on the inner side of the bill ofthe hook an extensionv provided. A retaining member.

or 'lug 6 is '.7 which is of s rino material is connected with the hook 3 and has the free end 8" thereof disposed to tit across the opening of the hook and bear on the inner side of the lug G, substantially as 1s shown in F ig. 2, so. that when the trace 5 is fitted upon the hook and thisl retaining member 7 springs against the lug 6, the retaining member will be disposed to guard against accidental or casual displacement of the trace from the hook, and at the same time this retaining member will be held by the lug 6 against being bent through strain placed thereon.

In the present instance I have shown the retaining member as made from a length of spring Wire which is looped about the body portion of the hook 3 and is then eX- tended to be looped and secured around the ferrule or ring 1, as indicated at 9.

As is shown in Fig. 3, the retaining member 10 is looped about the body of the hook 3, as shown at 1l, and the end of this retaining member is passed through a lug or enlargement 12 on the ferrule or ring 1. While either of these manners of fitting the retaining member might be resorted to, and in these adaptations it would be preferable that spring Wire be used, ribbon metal might be employed, and the secureinent of the retaining member might be accomplished in other Ways than disclosed.

From the foregoing it is seen that I have provided a swingletree hook which is of substantially standard form in its construction and design, and which has associated With the standard parts thereof, a retaining member so mounted and disposed that this member is very readily ressed aside t0 permit fitting of a leather, o lain, or other form of trace, and which retaining portion yvill through its own resiliency spring back 1n place to close across the opening of the hook to thus guard against accidental or casual displacement of the trace from the fitted and connected relation.

While I have in the foregoing description set forth only certain forms and constructions of the parts and have only hinted other changes, it Will be of course understood that variations and mechanical assignments might be resorted to without departlng from the spirit and scope of my invention, 1n view of which fact- Iv Wish to be rammen Feb. 19, isis.
